Apple has become the most valuable company in American history.

　　On Monday, its surging stock propelled the company's value to $623 billion, beating the record for market capitalization set by Microsoft Corp. in the heady days of the Internet boom.

　　Apple's stock has hit new highs recently because of optimism around what is believed to be the impending launch of the iPhone 5, and possibly a smaller, cheaper iPad.

　　Apple Inc. has been the world's most valuable company since the end of last year.

　　It is now worth 53 percent more than No. 2 Exxon Mobil Corp.

　　Apple's stock hit $664.74 in midday trading before retreating slightly to $663. That was $14.98, or 2.3 percent, higher than Friday's close.

　　Microsoft's 1999 peak was $620.58 billion, according to Standard &Poor's.

　　The comparison to Microsoft does not take inflation into account. In inflation-adjusted dollars, the software giant was worth about $850 billion on Dec. 30, 1999.

　　Microsoft is now worth $257 billion.

　　Analysts believe Apple's stock has room to grow. The average price target of 38 analysts polled by FactSet is $745.80.

　　Apart from the iPhone and 'mini iPad', analysts are speculating that Apple plans to make a TV set to complete its suite of consumer electronics products.

　　蘋果公司已經(jīng)成為美國歷史上市值最大的公司。

　　本周一，蘋果的股價一路飆升，公司市值漲至6230億美元，打破了微軟公司在網(wǎng)絡(luò)迅速發(fā)展的激情時代創(chuàng)下的市值紀錄。

　　蘋果公司股價在近期創(chuàng)下新高，原因是人們對蘋果被認為即將上市的兩大產(chǎn)品——iPhone 5和可能體積更小、價格更低的iPad普遍持樂觀的態(tài)度。

　　自去年年底以來，蘋果公司一直是世界上市值最高的公司。

　　現(xiàn)在蘋果公司的市值比第二名的埃克森美孚公司的市值多出了53%。

　　蘋果的股價在午盤交易時達到664.74美元，之后略微下滑，降至663美元。收盤價格比周五收市時高出14.98美元，即2.3%。

　　根據(jù)權(quán)威金融分析機構(gòu)標(biāo)準(zhǔn)普爾的數(shù)據(jù)，微軟公司1999年的市值最高峰是6205.8億美元。

　　這次蘋果與微軟的市值對比沒有將通貨膨脹的因素考慮在內(nèi)。如果按通脹率做出調(diào)整，微軟這一軟件巨頭在1999年12月30日的市值相當(dāng)于今天的8500億美元。

　　微軟公司如今的市值為2570億美元。

　　分析師認為，蘋果的股價仍然有上漲的空間。根據(jù)金融分析機構(gòu)FactSet的調(diào)查，38位分析師對蘋果公司做出的平均估價為每股745.8美元。

　　除了iPhone和迷你iPad之外，分析師還推測蘋果公司計劃制造電視機，從而打造完整的消費電子產(chǎn)品系列。
